PARALLEL PROCESSOR SYSTEM EQUIPPED WITH PERFORMANCE MEASURING CIRCUIT AND METHOD FOR MEASURING PERFORMANCE OF PROGRAM

摘要

PROBLEM TO BE SOLVED: To measure an access time or the number of times of access for each processing or each processor. SOLUTION: The values of measuring counters 51 and 52 are initialized, and a measuring ID value corresponding to a processing content is set in measuring ID registers 71-73 of each processor 61-63. When a processor performs access to a synchronizing register 2, the measuring ID value is transmitted to a measuring counter control circuit 3, and when any processor succeeds in access a shared resource a count-up circuit 4 outputs a prescribed count-up instruction signals to the measuring counter 51 or 52 corresponding to the inputted measuring ID value. The measuring counter measures a clock signal in a prescribed procedure, and when all the prescribed processing are ended, the measured values of the measuring counters 51 and 52 are read, and transmitted to a prescribed processor.
